Often your emotions are so stirred up that it can be very difficult to come up with words of condolence for those that need them. They have a lot of positive effect because something which is beautifully written and sensible expressed can actually have a soothing effect on the bereaving.
Like all particulars of the funeral the music should reflect the individual personality of the deceased. A eulogy is usually delivered as a speech at a funeral service. Having a memorial poem or poetry to look back upon can really be an emotional strengthener.
A poem comes from the heart, is a fitting tribute to the dead and the living to be remembered in time. If the deceased was a practical joker or light-hearted individual, maybe a poem that incorporates a bit of humor would remind their family of what a happy spirit that individual was. People often wonder whether it's proper to include humor in a eulogy.
And it doesn't end after death. Grief is not something we can simply set aside.
